Thank you to all my code masters for all their assistance, i was able to get a javascript that can do the job for me see below : "javascript" > function sumUp() { document.getElementById( ' ' ).value = parseFloat(document.getElementById( ' ' ).value) + parseFloat(document.getElementById( ' ' ).value); } all i need to do is just to repeat sumUp to sumUp1() .......sumUpN() then add to your TextBox onKeyUp="sumUp()" Thank you all again i appreciate you all

If your using datagrid view or similar control You can dynamically add the textbox references in the template itself. Wait let me search for the code.

Many Thanks Nigel, but how can i assign TextBox ID to a Javascript module when you have so many Textbox, that need to aggregate to a single textbox in row. what i mean each row have a gray shade textbox TxTotal that is the aggregate textbox so when you type 12 on T1 it send to TxTotal when you type 15 on T2 it sum up on TxTotal to be 27 so on. And the JavaScript i use is function reFocus(id) { document.getElementById(id).blur(); document.getElementById(id).focus(); } "t1" runat= "server" ontextchanged= "t1_TextChanged" onKeyUp= "reFocus(this.id);" AutoPostBack= "True" > "t2" runat= "server" ontextchanged= "t2_TextChanged" onKeyUp= "reFocus(this.id);" AutoPostBack= "True" > any help please my code masters
